Camera system with color display and processor for reed-solomon decoding

A camera system comprising:

• a substrate having a coding pattern printed thereon, said coding pattern employing Reed-Solomon encoding, wherein a data block of the coding pattern comprises:
• a plurality of target structures and a data area containing encoded information, the extent of the data area being defined by the target structures;
• and
• a handheld digital camera device comprising:
• a digital camera unit comprising a first image sensor for capturing images and a color display for displaying captured images to a user;
• and
• an integral processor configured for:
• controlling operation of the first image sensor and color display;
• decoding an imaged coding pattern printed on the substrate;
• and
• performing an action in said handheld digital camera device based on the decoded coding pattern, wherein said decoding comprises the steps of:
• detecting the target structures defining the extent of the data area;
• determining the data area using the detected target structures;
• and
• Reed-Solomon decoding the coding pattern contained in the determined data area.
